Winnie the War Winner was a radio set built by Sparrow Force during the Battle of Timor in 1942. The radio re-established contact between Sparrow Force and the Australian Army in Darwin on 19 April 1942. At the time, the Allies believed that Sparrow Force had been captured by the Japanese Army. By then, Sparrow Force had fought a guerilla campaign isolated from Australia for 60 days.[citation needed] The radio is currently on display in the Australian War Memorial in Canberra.
